MOTOR.

Specification of Letters Patent. Patented Mar. 11, 1919.

Application filed November 22, 1917. Serial No. 203,337.

To all whom it may concern:

Be it lmown that I, JosEPH A. SIMMs, citizen of the United States, residin at De tro1t, countyof Wayne, State of ichigan, have lnv'ented a certain new and useful Improvement in Motors, and declare the followin to be a full, clear, and exact descrlptlon of the same, suchas will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relatesto acombined inter- .nal combustion engine and steam engine; the construction being such that the heat from the exhaust gases and also the radiation re-' sulting from the operation of the internal combustion cylinder, or cylinders, is utilized to generate steam for delivery to the cylin de'r of the steam engine,the pistons of the respective cylinders bein adaptedto act upon the same crank-shai t.

It is well known in this art that the ther- .m'al efliciency of the average gasolene or kerosene. engme is only about 27% and that the other 73% is .lost. The most eflicient engine known at present shows a thermal efiiciency of 38%,; but owing to high compression,approx1mately 500. pounds per square inch,this type of engine isnecessarily of very heavy construction and therefore impracticable for aeronautic purposes- It is t ereforeone of the objects of this invention to rovide. an economical motive power especlally applicable to air vehicles.

A further object of 'this invention is the elimination of the usual starting devices, the reversing gear with its resulting weight, by the em oyment of a steam engine forming part 0 the power unit and whereby the motor may be started and itsv operation reversed.

A further object is to provide for the operation of this device independent of the operation of the internal combustion engine, whereby n an emergency the steam side of .ment of the invention. herein described with- -out departing from the spirit of the same.

The accompanying drawing is a diagrammatic, vertical, cross-sectional view of a mo- .tor embodying my invention,with parts in elevation;

, Referring to the letters of reference spread upon the drawing: A denotes a four cycle internal combustion engine, and B, a

separate double acting steam cylinder operating upon a crank-shaft C. A, indicates a water jacket surrounding the cylinder of the internal combustion engine, servin as a steam boiler for the steam cylinder%3. D, denotes a coil in'the water jacket through which passes the exhaust gases from the internal combustion engine for heating the surrounding body of water.

steam cylinder to warm the latter. D. is a pipe leading from the jacket B", for the discharge of the exhaust gases.

A, indicates the piston of the combustion lattera1so connected with the crank shaft C':the present embodiment showing both pitmen connected with the same throw of the crank shaft,this however is not essential.

I I The coil D, is also connectedwith the jacket B", of the a, indicates'a steam dome with which the j acket A, of the combustion cylinder is connected. 1 E, is a steam pipe connecting the steam dome with the steam chest of the cylinder B. F, indicates a'slide valve for corrtrolling the admission of steam to the cylinder, and F, is a rod for operating the valve, actuated in the usual manner from the crank shaft C, G, G are the steam inlet ports, of the cylinder, controlled by the slide valve F. G, is the exhaust port of the cylinder.

H, designates a fuel supply pipe connected with a carbureter I,'-preferably of the kerosene-gasolene type, inturn connected by a fuel pipewith the chamber of the inlet valve the motor may continue the-services of the NJ, 'controllingthe admission of fuelto the proceeds, the invention further-resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood Y that changes may be made in the embodider into the coil "D.

valves J, and K, are controlled through leve'rs actuated by a suitable cam shaft L, in

combustion chamber of the engine.

K, designates a valve congolling the delivery of the exhaust ases om the cyline operation of the the usual manner. M, indicates dia ammatieally a blow-burner connected wit the- 'coil D, to start the generation of steam, it

The er;- haust gases from the combustion engine passing out through the coil in the Water jacket, generating steam which is delivered to the steam cylinder to actuate the piston of thellatter as previously indicated d a manner readily understood.
